Hoffa was last seen at a Bloomfield Township restaurant on July 30, 1975, and his whereabouts have long been rumored to have him buried in various spots around the country, including locations in Oakland County.

An upcoming episode of “History Detectives” promises to explore recently declassified government files which reveal “shocking evidence of corruption at the highest levels,” according to the show’s website.

The program is expected to include interviews with a former mob lawyer, a murder witness and an FBI agent as the episode attempts to finally answer “Who Killed Jimmy Hoffa?”
